Pharmaceutical co-crystal: An alternative strategy for enhanced physicochemical properties and drug synergy

Abstract

A growing number of co-crystals in the literature are proof of how significant the co-crystallization concept has become. Co-crystallization enhances physicochemical properties through the formation of intermolecular interactions between a drug and a co-former. A co-crystal is a single crystalline material consisting of at least two molecular components solid at room temperature and present in a definite stoichiometric ratio. Pharmaceutical co-crystals consist of the active pharmaceutical ingredient and the co-former selected from generally regarded as safe (GRAS) list of the United State Food and Drug Administration.
